Etsy will be added to the S&P500 on September 21st. This puts more eyes on ETSY, a website where mom and pop can sell goods online. History tells us that stocks tend to fall after they are added to the index for the first few days but tend to be up for the next few days after the announcement. As you see on the weekly chart it is a sell signal but there is a caveat there could be a high volume breakout through the 10WMA moving average and keep going past the $129.94 high next week would make this stock a buy. Looking at the after hours it has already gapped up past the 10WMA and might be on the way to past $129.94. Once it gets past I would like to see no more pull back to the 10WMA. Sideways/Up action would be find as long as it is away from the 10WMA. If it hit and closes 2% below the 10WMA then it is time to see. We shall see though. Becareful of the overall market there are signs of weakness. Fundamentals look great as shown below:
